Nice, I've actually been thinking of making a photo verification site where you send your username, then print out a generated pdf like this that has a slightly more complex grid and some unique IDs per your username and session (so you can't use someone else's pic). Require a decent resolution and using some techniques I won't mention here to detect photoshop and scaling cheating, have someone validate the pic. Then if they check out, give them an image they can link to from their signature that shows they are verified. The link on the image goes to a page on the validation site showing they are indeed legit.
